BACKGROUND OF THE INVENTION

1. Field

This application generally relates to exercise device, specifically to a portable exercise device kit with assembly parts which can be easily assembled to allow leg exercise in a limited space and time.

2. Prior Art

The lifestyles of most sedentary office workers lead to long hours of little movement, especially on the lower body, resulting in health and muscular discomfort, including obesity. Prolonged immobilization or sedentary position may not only generate discomfort, especially on the lower-body, but increasing medical studies are reporting the close connection with health risks such as blood circulatory difficulties, obesity, deep-vein thrombosis, varicose vein, mental state decrease and/or other problems. Such immobile circumstances are especially developed for long distance travels, including air flights, trains, buses, cars . . . etc., which leave the passengers in immobile situation under a limited space for extended hours, accelerating fatigue, swelling of the lower body and discomfort.

Numerous portable exercise devices that provide exercise function while being foldable or having assembly parts, have been introduced for the user to travel with the exercise device to apply the exercise device in different locations and circumstances. The following examples are of typical prior art to this field of endeavor.

However, most prior art describe devices that require certain space for exercise or a subject to adjust the exercise device to. Moreover, considering that the majority users would use these devices in the office or in a compact space, such as in an airplane, little but efficient movement for the legs is important. Yet most exercises provided by the mentioned prior art devices involve large motion range to exercise. Otherwise, some prior art describe devices that may be carried for travelling but is rather heavy and does not allow leg exercise, which is the most immobile part of the body when working sedentarily or traveling in a compact space.

Health related studies show that exercising the lower body, such as thighs and calves where large amount of muscles are formed, burns more calories while it also prevents deep-vein thrombosis, varicose vein and other blood circulatory troubles, thus is especially recommended for people with extended stationary or sedentary position

Advantages of this application of one or more aspects are to provide a convenient, compact and light leg exercise device without requiring additional space or furniture, and which provide efficient leg movements without distracting the crowd around the user with excessive movements. Other advantages of one or more aspects are to provide variations of leg exercise, such as stepping motion, ankle stretch and thigh contraction, which may be practiced simultaneously while performing other activities such as conventional office work, doing simple works at a table or desk, watching television or video games or being seated in an airplane or long distance bus, without requiring much space other than seated and footing area of the user. This application describe device that is quiet enough to exercise in the office or small space without disturbing others. These and other advantages of one or more aspects will become apparent from a consideration of the ensuing description and accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Most preferred embodiment of a portable leg exercise device kit (1) is shown in FIG. 1 and FIG. 2. The device kit is composed of main device kit case (10) which contains leg exercise assembly inside. The leg exercise assembly of the preferred embodiment of said device includes one or more pairs of elastic support poles (20), a pair of slippers (30), and a pair of streamline shaped thigh wings (41) which can be connected with one of the elastic support poles (20).

As illustrated in FIG. 1 and FIG. 2, the case (10) is a convenient portable bag form for carrying, and contains the exercise assemblies together inside. Inner surface of the case (10) has one or more projected pole lock base (11) on each side of the case (10) for placing and locking elastic support poles (20). Said projected pole lock base (11) is projected in an angle of similar given angle between user's foot and leg, to provide ease and comfort for the user's ankles when exercising, since the case (10), when fully opened, serves as the base for the leg exercise. Said lock base (11) includes base groove (11 a) and cross-shape groove (11 aa) to connect with elastic support pole (20). On the external part of the case (10) exists one or more anti-sliding rod (12) to prevent the said device kit (1) from sliding or walking around the ground when exercising, due to the force given by the user and resistance provided by the elastic pole (20). The anti-sliding rod (12) can be unfolded to stand against a wall or subject in front, usually a desk or front seat.

As illustrated in FIG. 2 and FIG. 3, one or more pairs of elastic poles (20) is composed of lower pole shell (21) that include lower pole flange (21 a) with lower pole cross-shape tongue (21 aa), and upper pole shell (22) which include upper pole flange (22 a) with upper pole cross-shape tongue (22 aa), containing springs (23) inside. The slippers (30) contain a slippers footboard (31) with a front footboard (31 a), a center footboard (31 b) and a heel footboard (31 c). The slippers footboard (31) is divided into three parts to allow easier foot and ankle stretch motions. On each front footboard (31 a) and heel footboard (31 c), there is corresponding front footboard lock base (31 aa) and heel footboard lock base (31 ca) which serves as a groove to lock the elastic support pole (20). On the upper surface of the slippers (30), acupunctural cushions (32) are provided to stimulate blood circulation and ease tension of the user's feet. Said acupunctural cushions (32) may be bumpy surfaced cushions filled with air or hard bumpy surfaced rollers. The streamline shaped thigh wings (41) have thigh wing lock groove (41 a) on the convex surface, similar to the base groove (11 a), to connect the two thigh wings (41) with one elastic support pole (20).

The portable leg exercise device kit (1) can be assembled easily by taking the elastic support poles (20) and placing them over each projected pole lock base (11) on one end, and the slippers' front footboard lock base (31 aa) and heel footboard lock base (31 ca) on the other end. When placing the elastic support poles (20) into the projected pole lock base (11), the lower pole cross-shape tongue (21 aa) can be placed over the cross-shape groove (11 aa), as the upper pole cross-shape tongue (22 aa) can be placed over the front footboard lock base (31 aa). The same process is applied for all elastic support poles (20) to each projected pole lock base (11) and all the front footboard lock bases (31 aa) and the heel footboard lock bases (31 ca) of each slipper. When assembling, user can use the longer elastic support pole (20) for the front footboard (31 a), and the shorter elastic support pole (20) for the heel footboard (31 c), since the support pole (20) lengths are different from each pair. The user can then turn the support poles (20) either left or right to fix itself with the case (10) and the slippers (30), by locking the lower pole cross-shape tongue (21 aa) with the base groove (11 a) and the upper pole cross-shape tongue (22 aa) to the front footboard lock base (31 aa). Same logic applies to the rest of the elastic support poles (20) of each end, with projected lock bases (11) and slippers (30).

FIG. 4A and FIG. 4B show examples of exercises which may be practiced with the assembled portable leg exercise device kit (1). Other than stepping exercise which is available by pressing down each leg at a time or simultaneously, user can also stretch the ankles or release tension on the feet and calves by pressing down the front foot and heels by turns as shown in the two illustrations, FIG. 4A and FIG. 4B.

FIG. 5 illustrates an exploded view of an alternative embodiment of the said portable exercise device kit, connecting the elastic support pole (20) with the two thigh wings (41). The support pole locking logic is equal to the pole locking logic described for locking the case (10) and the slippers (30) with elastic support pole (20). The streamline shaped thigh wings (41) have a thigh wing lock groove (41 a) on the convex surface to connect the elastic support pole (20). When both ends of the elastic support pole (20) is fixed with the thigh wings (41), the user can apply alternative thigh exercise by placing the assembled thigh exercise assembly (40) between the user's inner thighs, then straining against the elastic force with the thighs, by pulling the thighs towards each other.

FIGS. 6A and 6B illustrate one of many examples of alternative embodiment of the portable leg exercise device with the elastic support pole (20″) directly connected to the case (10) and the slippers (30), which does not require assembling action for the user. The elastic support pole (20″) is directly connected to the pole lock base (11″) and the slippers' front footboard lock base (31 aa″) and heel footboard lock base (31 ca″). This alternative embodiment also has different length of the elastic support pole (20″) between the front and the heel of the slippers (30), therefore to effectively minimize the case (10) size, each slipper's direction is reversely overlaid on top of each other when the case is closed, as shown in FIG. 6A. However, the user can align one side of the case (1) by detaching hinge joint tongues for closing (13 a), away from hinge joint grooves (14) of other side of the case (1), then turning the direction around to align the two slippers in the same direction, and placing hinge joint tongues for operation (13 b) in the hinge joint grooves (14). Case closing lock (15) on the handle part of the case (1) is a hook formed lid type which holds the hinge joint tongue for operation (13 b) when the case (1) is closed for portability.
